perf(search): count collection bookmarks via SQL aggregate - #229
Conversation
Semantic collection search computed each collection's bookmark count by loading every full Bookmark record just to call .len(), an N+1 bottleneck as collections and result sets grow. Add Database::count_bookmarks_in_collection, a lightweight COUNT(*) over collection_bookmarks, and use it in collection_semantic_search. Preserves the existing zero-on-error behavior. Closes #181.

📝 WalkthroughWalkthroughSemantic collection search now obtains bookmark counts with a dedicated SQL aggregate. The storage layer adds ChangesCollection bookmark counts
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The PR improves bookmark counting in the CLI search path, but the TUI search path still loads full bookmark records and the new database operation lacks diagnostic tracing. This leaves a bounded performance and observability gap, so the change is mergeable with explicit owner follow-up. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Greptile SummaryThe PR replaces collection bookmark materialization during semantic search with an exact SQL aggregate while retaining the existing zero-on-error behavior.
Confidence Score: 5/5The PR appears safe to merge with no actionable correctness, security, or build issues identified. The aggregate counts the same constrained collection-membership rows needed by semantic-search results without materializing bookmark records, and its caller preserves the established error behavior.

Add the required database trace event.
Line 631 adds a database operation without a tracing event. Emit tracing::debug! with target "codemark::db" and the collection_id before the query.
Proposed fix

+ tracing::debug!(
+ target: "codemark::db",

let count = self.conn().query_row(As per coding guidelines, instrument new Rust functionality with tracing::debug! using the matching codemark:: subsystem target.

Semantic collection search computed each matched collection's bookmark count by loading every full
Bookmarkrecord just to call.len(), an N+1 bottleneck as collections and result sets grow. This addsDatabase::count_bookmarks_in_collection, a lightweightCOUNT(*)aggregate overcollection_bookmarks, and uses it incollection_semantic_searchwhile preserving the existing zero-on-error behavior. A unit test verifies the count matches the full-list length and returns 0 for empty/unknown collections. Closes #181.🤖 Generated with Claude Code
